Other versions included the Mk III (simpler and cheaper to produce) and the Mk V (featuring a wooden stock and pistol grip). These variations, each with minor differences, represent the evolution of the design to meet the changing needs of the war. This diversity adds to the allure for collectors seeking to own a specific model.

A Sten SMG parts kit represents a collection of components salvaged from an original Sten gun. These kits can vary considerably in their completeness, condition, and the presence of original versus reproduction parts. They are typically assembled from deactivated or surplus weapons. The parts kit offers a fascinating glimpse into the inner workings of the Sten gun. These kits are often the starting point for building a legal, functioning firearm.

The components found within a Sten SMG parts kit usually include, but are not limited to the following:

The receiver: This is arguably the core component of the Sten gun’s structural integrity, housing the bolt, barrel, and trigger mechanism. Due to the legal implications and restrictions surrounding the receiver, this can often be either the original or a replacement. The construction of the receiver varies, so it is often a critical component for builders.

The bolt: The bolt is the heart of the Sten gun’s operating system. It houses the firing pin and extracts and ejects spent casings. The bolt’s dimensions and operation are critical to the gun’s ability to function.

The barrel: The barrel guides the bullet as it travels from the chamber, imparting the spin that stabilizes it in flight. Barrels are often worn from use, and kits may include a new or used barrel.

The trigger mechanism: This assembly, including the trigger, sear, and related springs, controls the firing process. Different variants of the Sten gun may use variations of this system.

The magazine housing: This component houses the magazine, holding the ammunition ready for feeding into the gun. The magazine housing on Sten guns is frequently attached to the side or bottom of the receiver.

The stock: This is the component that the user places against their shoulder to control the weapon. Sten gun stocks varied, with some being wood or metal.

Various small parts: Pins, springs, screws, and other minor parts are often included in a parts kit, sometimes essential to the operation of the firearm.

Components Typically NOT Included

It is crucial to note what is not typically included. The receiver or receiver tube is often a critical area of restriction. While some kits may contain a deactivated receiver, the legality of owning or modifying such a part is highly dependent on local and national regulations. Kits often may or may not include the magazine. Finally, some kits do not contain the required tools for assembling or building the firearm.
